Robert West was the son of Sir Thomas West, 2nd Baron de la Warr and wife Anne Knollys. He was born 3 Jan 1575 in Wherwell, Hampshire, England1574, and predeceased his father, which means he died before 1601. [1594, per History of Parliament Online.]

It is often reported that he married Elizabeth Coks (or Cox or Cock). This may be an error.[It apparently isn't.] His nephew Robert West, son of Thomas West III, is also reported as marrying a lady of the same name. See http://thepeerage.com/p24497.htm.
